Circuit Simulator Applet

This is an electronic circuit simulator.  When the applet starts up you will see
an animated schematic of a simple LRC circuit. The green
color indicates positive voltage. 
The gray color indicates ground. 
A red color indicates negative voltage.  The moving yellow dots indicate current.

To turn a switch on or off, just click on it.  If you move the mouse over any component of the circuit, you
will see a short description of that component and its current state in the
lower right corner of the window.  To
modify a component,
move the mouse over it, click the right mouse button (or control-click
if you have a Mac) and select “Edit”.

The “Circuits” menu contains a lot of sample circuits for you to try.
